Remove first element of a Stream in Java 8

问题

I have generated a Stream in Java 8 with Files.walk() method from java.nio library. The problem is that the method includes by default the root path but I do not want this element. I have solved in this case with this code using filter() method:

public void listFiles(String directoryPath) {
    try {
        Path root = Paths.get(directoryPath);
        Files.walk(root,1)
            .filter(x -> !x.equals(root))
            .forEach(System.out::println);
    } catch (IOException ex) {
        System.err.println("Error reading file: " + directoryPath);
    }
}

My question is if there is a way more elegant to remove the first element of a Stream than this. For example working with a index in the Stream or with a tail() method as others functional languages.

回答1:

Use skip(1) to ignore the first element.

Don't use it with parallel streams without reading the disclaimer in the javadoc.
